Box around pointer on Macs after calibration

ColorGeek factor:

Some users have noticed that a small square appears around the pointer on screen after calibration with certain software on newer Macs.

This square is actually the "mask" used by the OS for the pointer. Calibrations that result in non-zero values at the ends of the calibration curves reveal a bug in Nvidia video card drivers with versions earlier than 2.4

The Fix:

Run the Software Update control panel and let it upgrade the MacOS to version 9.2.2. This will install the Nvidia 2.4 drivers and the problem will be corrected.

Thanks to Neil Snape, Roger Schutte and other users on the ColorSync mailing list for the update information.
